Question

When processing milk, the liquid goes through homogenization, pasteurization, chilling, and packaging. These are examples of what?

1) Food preservation techniques
2) Milk processing steps
3) Dairy industry practices
4) Milk packaging methods

Answer 1

Homogenization, pasteurization, chilling, and packaging are steps in milk processing, where milk is treated for safety and quality before being distributed for consumption. The correct option is 2).

Step-by-step explanation:

When processing milk, the mentioned steps of homogenization, pasteurization, chilling, and packaging are examples of milk processing steps. These steps are part of the overall dairy industry practices to ensure that milk is safe for consumption and retains its quality over time.

Homonization ensures that the fat droplets are evenly distributed throughout the milk, preventing cream from separating.

Pasteurization is a critical step where milk is heated to a specific temperature to kill pathogens and reduce microbial content; this can be done using the High Temperature Short Time (HTST) or the Ultra-High Temperature (UHT) methods.

The UHT pasteurization, in particular, involves heating milk at 138 °C for 2 or more seconds. Chilling quickly cools the milk to slow microbial growth, and finally, packaging the milk maintains its quality and extends its shelf life.

These steps are essential for delivering a product that is both safe and pleasant to drink, while also having a reasonable shelf life. Option 2) is the correct one.
